REGULATORY TEXT:  
90-05-11 BRITISH AEROSPACE: Amendment 39-6525. Docket No. 89-NM-233-AD.
Applicability: Model BAe 146-100A and -200A series airplanes, as listed in British Aerospace Service Bulletin 57-24-00911A, Revision 1, dated May 1, 1988, certificated in any category.

Compliance: Required within 180 days after the effective date of this AD, unless previously accomplished.

To prevent inability of the flap system to sustain expected loads and prevent reduction of airplane controllability, accomplish the following:

A. Install new roller bearing pins at the forward top position on the right and left flap track No. 3 lower carriage assemblies, in accordance with British Aerospace Service Bulletin 57-24-00911A, Revision 1, dated May 1, 1988.

B. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Northwest Mountain Region.

NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who will either concur or comment and then send it to the Manager, Standardization Branch, ANM-113.

C. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD.

All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to British Aerospace, Librarian for Service Bulletins, P.O. Box 17414, Dulles International Airport, Washington, D.C. 20041. These documents may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 17900 Pacific Highway South, Seattle, Washington, or the Standardization Branch, 9010 East Marginal Way South, Seattle, Washington.

This amendment (39-6525, AD 90-05-11) becomes effective on April 9, 1990.
